DHCP Option Data Types

Each DHCP option is identified by a name and an option code number, and specifies a data type. The data type for predefined options is predefined. For example, in the DHCP option space, the data type for option 1: subnet-mask is an IP address. You cannot change the data type for this option.

BloxOne DDI supports predefined options that contains the following standard option codes:
